Most options are reliant on the Michael 6 genitalia, as it needs those base files to convert to Genesis 2 Female. The other options are reliant on Michael 5, and will work on Genesis 2 Female with the various offerings that handle that conversion.

There is no option to simply put Genesis Male genitalia on Genesis Females (1 or 2). You MUST use the conversion files/scripts bought separately, and for those to work, you MUST have the full Pro bundle of the male figure whose genitalia you wish to use.

Satanica's Real M3 Gens will work on any figure, but it must be placed manually on the figure, and still requires the Michael 3 Pro bundle, as well as several add-ons from Satanica to be completely functional (unless he's updated that to include everything in one low price).
